Heat oven, prepare baking sheet: Preheat oven to 450 degrees. Spray a rimmed 18 by 13-inch baking sheet with non-stick cooking spray.
Place potatoes in a mound in center of baking sheet. Drizzle with olive oil.
Sprinkle potatoes with salt, pepper, garlic powder, paprika and onion powder. Toss well to evenly coat in oil and spices.
Spread potatoes even into a single layer. Bake in center of preheated oven 15 minutes.
Toss potatoes, continue to bake: Remove from oven, toss and continue to bake until just tender, about 15 minutes longer.
Broil potatoes briefly: Move oven rack about 5-inches from broiler. Broil potatoes about 2 – 3 minutes until slightly browned (keep a close eye on them and don’t walk away they can brown quickly!).
Toss and continue to broil if desired for more browning: Remove and toss, continue to broil until golden brown and crisp on opposite side a minute or two longer. Serve warm.
